Substrate supply apparatus

Abstract

A substrate supply apparatus includes a substrate-accommodating section for accommodating a substrate on which electronic components are to be mounted, a substrate-width-adjusting device, a transporting device, a substrate-sucking device, and an elevating device. The accommodating section has substrate-width-regulating sections a distance between which can be adjusted in a width direction of the substrate. The adjusting device adjusts the distance between the regulating sections by moving one of the regulating sections in the width direction. The transporting device is supported by the regulating sections, has a pair of rails, is arranged above the accommodating section, and transports the substrate to an electronic component-mounting apparatus. The sucking device has a long substrate-sucking arm and a plurality of short substrate-sucking arms. Each of the substrate-sucking short arms is position-changeably installed on the long substrate-sucking arm. The elevating device supports and vertically moves the sucking device so that the sucking device transfers the substrate to the transporting device. The elevating device is disposed at a center of a space between the pair of rails in the width direction.

What is claimed is: 
     
       1. A substrate supply apparatus comprising: a substrate-accommodating section for accommodating a substrate on which electronic components are to be mounted, the substrate-accommodating section having substrate-width-regulating sections a distance between which can be adjusted in a width direction of the substrate;   a substrate-width-adjusting means for adjusting the distance between the substrate-width-regulating sections by moving one of the substrate-width-regulating sections in the width direction;   a transporting means, supported by the substrate-width-regulating sections, having a pair of rails, and arranged above the substrate-accommodating section, for transporting the substrate to an electronic component-mounting apparatus;   a substrate-sucking means having a long substrate-sucking arm and a plurality of short substrate-sucking arms, each of the substrate-sucking short arms being position-changeably installed on the long substrate-sucking arm; and   an elevating means for supporting and vertically moving the substrate-sucking means so that the substrate-sucking means transfers the substrate to the transporting means, the elevating means being disposed at a center of a space between the pair of rails in the width direction.   
     
     
       2. The substrate supply apparatus as claimed in claim 1, wherein one end of the long substrate-sucking arm is position-changeably installed on the elevating means. 
     
     
       3. The substrate supply apparatus as claimed in claim 1, further comprising a width-adjusting means, operably connected with the substrate-width-adjusting means, for positioning the elevating means at the center of the space of the substrate-accommodating section in the width direction in unison with an operation for adjusting the distance between the substrate-width-regulating sections of the substrate-accommodating section to a width corresponding to that of the substrate.
